Equally Qualified
Congratulations,
You’re hired!
Communication: Success
Excess Gingival Display
Excessive gingival display negatively affected how attractive a person's smile is judged to be. In addition, how friendly, trustworthy, intelligent, and self-confident a person was perceived to be was inversely related to the amount of gingival display. Laypeople were just as sensitive to these differences as dental students.

Introduction to Smile Design
•There are rules•Rules are made to be
broken•No one smile ever
follows all the rules
•Let’s start with a blank canvas
•Where do we begin?
Designing an Ideal Smile
Incisal edge is starting point!
•Incisal plane parallel to the interpupillaryline
Incisal Placement

Canted Incisal Plane
•Forehead - from Trichion to Nasion
•Cheek - Nasion to Subnasale
•Mouth - Subnasaleto Menton
Trichion
Nasion
Subnasale
Menton
Rule of Thirds
•Divide subnasale and menton into equal Thirds
•Incisal edge at junction of Superior and Middle Thirds
Incisal Edge
Rule of Thirds Incisal Plane too inferior
Incisal Plane too superior
•Appearance
Determinents of Incisal Edge Placement:

•Appearance•Phonetics
Determinents of Incisal Edge Placement:
Use words like “these, those, fifty five, very fine”
Pound- JPD 1970“Using speech to simplify
denture service”
“When the patient pronounces “f” and “v”sounds…the length and labiolingual position of the incisal edges of the maxillary teeth…can be determined.”
Incisal Edge Position:Phonetics
•Appearance•Phonetics•Occlusion
Determinants of Incisal Plane Placement:
•Vertical midline in the center of the face perpendicular to the interpupillary line
•Vertical midline centered with the philtum

Smile CurveReverse Smile Curve
•Incisal edges follow curvature of the lower lip

Central Incisors
• Geometric shape is trapezoidal
• Mesial crest of convexity is in the incisal third
• Distal profile is more convex and the crest of convexity is at the junction of the middle and incisal thirds
• Mesial incisal angle is almost a right angle, distal incisal line angle is rounded

Denture teeth often recommend tooth form to mimic face form

Lateral Incisors
• Smaller and more rounded than the central incisor
